Abstract
Description
Technical Field
[0001] This utility model relates to the field of rain gauge technology, and in particular to an automatic maintenance device for a tipping bucket rain gauge. Background Technology
[0002] A tipping bucket rain gauge is a commonly used rainfall measurement device that records rainfall by collecting rainwater and driving the bucket to tip over.
[0003] In actual use, impurities in rainwater can easily clog the rain gauge funnel, causing the tipping bucket rain gauge to malfunction. Traditional maintenance methods require manual cleaning of the rain gauge funnel and filter screen regularly, which is not only cumbersome but also inefficient. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies that require manual and regular cleaning of rain gauge funnels and filters, which is not only cumbersome but also inefficient. Therefore, this invention proposes an automatic maintenance device for tipping bucket rain gauges.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic maintenance device for a tipping bucket rain gauge includes a tipping bucket rain gauge body and a rain funnel fixed inside the tipping bucket rain gauge body, and further includes:
[0007] A fixed frame is provided on the tipping bucket rain gauge body, and a filter screen for filtering is fixed inside the fixed frame;
[0008] The bottom end of the fixed frame is fixed with a fixed ring, which is sleeved on the surface of the tipping bucket rain gauge body. A set of positioning components is provided inside the fixed ring, which is used to fix the fixed ring to the surface of the tipping bucket rain gauge body.
[0009] A fixing block is fixed to the surface of the fixing frame, and a rotating shaft is rotatably mounted on the top of the fixing block. A cleaning rod for cleaning the filter screen is fixed to the surface of the rotating shaft. A set of driving components is provided inside the fixing block, and the driving components are used to drive the cleaning rod to swing and clean.
[0010] In one possible design, the positioning assembly includes two nuts fixed to the surface of the retaining ring, each nut having a positioning screw threaded into it.
[0011] In one possible design, anti-slip pads are provided at the adjacent ends of the two positioning screws.
[0012] In one possible design, the bottom end of the fixed frame is fixed with a positioning ring that matches the rain gauge funnel.
[0013] In one possible design, the drive assembly includes a first groove formed within a fixed block, a rotating shaft extending downwards into the first groove, a driven gear fixed to the surface of the rotating shaft, a half-tooth ring sliding within the first groove, a drive rack meshing with the driven gear fixed to the side end of the half-tooth ring, a half-tooth gear intermittently meshing with the half-tooth ring rotating within the first groove, and a drive motor fixed to the bottom end of the fixed block, the drive motor being fixedly connected to the half-tooth gear via a coupling.
[0014] In one possible design, the bottom end of the fixing block is fixed with a protective shell for protecting the drive motor.
[0015] In this application, after the positioning ring in the fixed frame is placed into the rain gauge funnel along the inner wall of the rain gauge funnel, the fixed ring is sleeved on the surface of the tipping bucket rain gauge body. By turning the two positioning screws, the bottom ends of the two positioning screws are pressed into contact with the surface of the tipping bucket rain gauge body, so that the fixed frame and the filter screen are stably fixed on the tipping bucket rain gauge body.
[0016] During use, rainwater passes through the filter screen and enters the rain gauge funnel. The filter screen removes solid debris, effectively preventing clogging. Starting the drive motor rotates the half-gear, which in turn causes the half-gear ring to reciprocate linearly within the first groove. The half-gear ring then drives the drive rack to reciprocate linearly, which in turn drives the driven gear to oscillate reciprocally. The driven gear then drives the rotating shaft to rotate reciprocally. This reciprocating rotation of the shaft causes the cleaning rod to oscillate reciprocally, effectively cleaning the filter screen of solid debris and preventing clogging.
[0017] Beneficial effects: In this utility model, the automatic maintenance device for tipping bucket rain gauge can filter the rainwater entering the rain gauge funnel by setting a fixed frame and a filter screen, preventing impurities from clogging the rain gauge funnel and ensuring the normal operation of the tipping bucket rain gauge.
[0018] In this utility model, the automatic maintenance device for a tipping bucket rain gauge, through the design of the positioning component, can easily and firmly fix the fixing frame to the surface of the tipping bucket rain gauge body, ensuring the stability and reliability of the device;
[0019] In this invention, by setting up a drive component and a cleaning rod, the filter screen can be automatically cleaned without manual intervention, which greatly improves maintenance efficiency and convenience. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Example 1: Refer to Figures 1-4 A maintenance device includes a tipping bucket rain gauge body 1 as the base of the entire device, used to measure rainfall. Inside the tipping bucket rain gauge body 1, a rain funnel 2 is provided for collecting rainwater and guiding it into the measuring mechanism of the tipping bucket rain gauge body 1.
[0027] To filter the rainwater entering the rain gauge hopper 2 and prevent impurities from clogging it, a fixing frame 3 is installed around the tipping bucket rain gauge body 1. A filter screen 4 is fixed inside the fixing frame 3 to filter out impurities in the rainwater.
[0028] A fixing ring 9 is fixed to the bottom end of the fixing frame 3, and the fixing ring 9 is sleeved on the surface of the tipping bucket rain gauge body 1. In order to firmly fix the fixing ring 9 to the surface of the tipping bucket rain gauge body 1, a set of positioning components is provided inside the fixing ring 9. The positioning components include two nuts 10 fixed to the surface of the fixing ring 9, and two positioning screws 11 threadedly connected to the nuts 10. By screwing the positioning screws 11 into the threaded holes on the surface of the tipping bucket rain gauge body 1 and tightening the nuts 10, the fixing ring 9 can be fixed.
[0029] To further improve the stability of the fixation, anti-slip pads are provided at the close ends of the two positioning screws 11. The anti-slip pads can increase the friction between the positioning screws 11 and the surface of the tipping bucket rain gauge body 1, and prevent the fixing ring 9 from loosening.
[0030] To clean the filter screen 4 and prevent it from clogging, a fixing block 6 is fixed to the surface of the fixing frame 3. A rotating shaft 8 is mounted on the top of the fixing block 6, and a cleaning rod 5 for cleaning the filter screen 4 is fixed to the surface of the rotating shaft 8. When the rotating shaft 8 rotates, the cleaning rod 5 swings accordingly, thereby cleaning the filter screen 4.
[0031] To drive the cleaning rod 5 to perform oscillating cleaning, a drive assembly is provided within the fixing block 6. The drive assembly includes a first groove 14 formed within the fixing block 6, and a rotating shaft 8 extends downwards through the first groove 14. A driven gear 15 is fixed to the surface of the rotating shaft 8, and a half-toothed ring 17 slides within the first groove 14. A drive rack 16, meshing with the driven gear 15, is fixed to the side end of the half-toothed ring 17. When the half-toothed ring 17 slides, it drives the drive rack 16 to move, thereby driving the driven gear 15 and the rotating shaft 8 to rotate.
[0032] A semi-gear 18, intermittently meshing with a semi-gear ring 17, also rotates within the first groove 14. The rotation of the semi-gear 18 drives the semi-gear ring 17 to slide. To achieve the rotation of the semi-gear 18, a drive motor 13 is fixed to the bottom of the fixing block 6. The drive motor 13 is fixedly connected to the semi-gear 18 via a coupling. When the drive motor 13 starts, it drives the semi-gear 18 to rotate, which in turn drives the semi-gear ring 17, the drive rack 16, the driven gear 15, and the rotating shaft 8 to oscillate periodically, thereby achieving automatic cleaning of the filter screen 4.
[0033] To protect the drive motor 13 from rainwater erosion and damage, a protective shell 7 for protecting the drive motor 13 is also fixed to the bottom of the fixing block 6.
[0034] Example 2: Refer to Figures 1-4 An improvement based on Example 1: An automatic maintenance device for a tipping bucket rain gauge, which is applied in the field of rain gauge technology, wherein the bottom end of the fixed frame 3 is also fixed with a positioning ring 12 that matches the rain funnel 2. The positioning ring 12 can ensure the accurate alignment between the fixed frame 3 and the rain funnel 2, and prevent rainwater from flowing into the tipping bucket rain gauge body 1 from the gap between the fixed frame 3 and the rain funnel 2.
[0035] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 13 are commonplace and are all conventional methods or common knowledge. Therefore, they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
